Abstract

The present invention makes it possible to collect and deliver widely distributed, grid computing related resource information in a scalable manner with its use in mind. When collecting resource information on a CPU type and a usage ratio before using resources in a grid environment such as a CPU, a resource use device 100 sends a resource information evaluation expression 110, which is a criterion for selecting resources, to a resource providing device 120 via evaluation expression sending means 101. The resource providing device 120 evaluates resource information on a resource, which will be provided, via resource information evaluation means 121 using the resource information evaluation expression 110, adds a resource information value 131, which is the result of evaluation, to resource information 130 via resource information value addition means 122, and delivers the resource information 130 to the resource use device 100.
